Email sending problem

Hi all,

I set up Mautic on my server, do the CRON jobs and all but, when I want to send an email, it doesnt work. I use Sendgrid services to send it and when I want to connect it’s show me this error (pass and Id are well registred):

Unable to connect with TLS encryption Log data: ++ Starting MauticEmailBundleSwiftmailerTransportSendgridTransport << 220-server.graditest.com ESMTP Exim 4.86 #2 Fri, 20 Nov 2015 03:31:58 +0000 220-We do not authorize the use of this system to transport unsolicited, 220 and/or bulk e-mail. >> EHLO marketing.graditest.com << 250-server.graditest.com Hello server.graditest.com [162.144.202.98] 250-SIZE 52428800 250-8BITMIME 250-PIPELINING 250-AUTH PLAIN LOGIN 250-STARTTLS 250 HELP >> STARTTLS << 220 TLS go ahead !!

Anyone have an idea? is it from my server? something I missed?

Thx
